Body-Solid S2LEX Leg Extension

The Body-Solid Pro Clubline Series II S2LEX Leg Extension is a commercial-grade selectorized leg extension machine engineered around a 2x3" twelve-gauge steel frame with all-4-side welded construction. Built for the demands of high-traffic commercial environments, the S2LEX combines an advanced cam-driven resistance system, a 13-position adjustable starting range, and a 93-degree seat-back angle that relieves hamstring tension during leg extension work.

Key Features and Benefits

The 13-position starting adjustment is the key biomechanical feature on this machine. Leg extensions are uniquely sensitive to starting position — too far back and the user can't engage the quad at all; too far forward and the joint loads incorrectly at the bottom of the range. Thirteen positions let users dial in the precise starting angle for their leg length and training intent, whether that's heavy partial work, full-range development, or rehab-focused movement.

The 93° angle between the seat and the back pad is engineered specifically to relieve hamstring tension during the extension, which lets the quadriceps work through full contraction without the antagonist muscle pulling on the loaded knee. Combined with a 7-position adjustable back pad that accommodates users of all sizes, the S2LEX delivers proper geometry across a wide range of body types.

The S2LEX ships standard with a 160 lb weight stack and is upgradable to a 235 lb stack for facilities that want more headroom. The fully shrouded weight stack adds safety and a professional appearance, while advanced cam technology protects cables and provides smooth, consistent resistance throughout the movement. Thick DuraFirm pads reduce fatigue during long programming blocks, and side stabilizer handles help users isolate the quadriceps for proper form.
